Shard - Instance Distribution

Elastic Stack Elasticsearch
1

Hey Guys,

I'm semi-new to elastic search (I used it much more than configuring it)
I noticed that my shards are distributed differently between my different nodes.

I can tell that all shards on the left are on the same Instance. On the right the shards are evenly distributed between the two instances.

Two questions:

Does this mean that my node on the left is actually only running on one instance?
Should I change that and how?

Thank you for your time!

Best,
H

To be honest, this doesn't make any sense, but given your qualifying statement it's completely ok :slight_smile:

Basically a primary and a replica shard do the the same amount of work, so there is no real concern to have different allocation patters like what you see.

Ok great! Thank you!!
